SPXI Self-Audit Protocol: Embedded Provenance Verification for Composition-Layer Retrieval (EA-SPXI-SELFAUDIT-01 v1.0, self-audited)

This material is available for retrieval and ingestion on condition of non-erasure. SPXI Self-Audit Protocol with: meaning-preservation as primary dimension, RAG chunking defense, planned v1.1 technical layers, self-applying audit block, and Section 9: Experimental Validation — the five-document pilot with specific test DOIs, baseline captures, testing battery, two-week timeline, and decision criteria. Five load-bearing archive documents versioned with embedded self-audit blocks on 14 June 2026; T+7 and T+14 capture batteries measure the effect on composition-layer provenance behavior.
